About this study

Official title: Assessment of Left Atrial Function of COVID-19-recovered Patients During the Surge of Omicron Variants by Two-dimensional Speckle Tracking Echocardiography

The goal of this observational study is to retrospectively analyze left atrial function in mild to moderate COVID-19-recovered patients. The main questions it aims to answer are:

  • Whether left atrial function is involved in patients with mild to moderate COVID-19 after recovery.
  • What are the factors that may be associated with persistent heart-related symptoms (including chest pain, chest tightness, palpitations, shortness of breath, or postural tachycardia) in patients with mild to moderate COVID-19 ?

Participants will undergo transthoracic echocardiography to obtain conventional ultrasound parameters, two-dimensional strain parameters will been obtained through software post-processing, and general clinical data and laboratory test results will been obtained.

Read the detailed description

The included patients who recovered from COVID-19 infection and healthy people underwent transthoracic echocardiography at the First Affiliated Hospital of Shandong First Medical University from December 20, 2022 to January 20, 2023. Routine data and two-dimensional strain parameters of transthoracic echocardiography of the study subjects were obtained:

  1. The echocardiographic examination was performed using a Epiq 7C ultrasound machine, and images were acquired with the patient in left lateral decubitus using a 3.5-5 MHz transducer at a depth of 16 cm. ECG was recorded, and 3 consecutive cardiac cycles of each view were recorded during quiet breathing at 50-80 frames/sec. All patients were subjected to conventional transthoracic echocardiography \& Speckle tracking echocardiography (STE). All measurements were taken following the American Society of Echocardiography (ASE) recommendations.
  2. Left atrial strain analysis was obtained using automated speckle tracking software. The regions of interest were generated automatically and Left atrial endocardial border was manually adjusted when required. Left atrial phases definition and Left atrial strain values were measured from the Left atrial longitudinal strain curve according to the European Association of Cardiovascular Imaging (EACVI)/American society of echocardiography (ASE) guidelines. Global LV systolic strain was evaluated, and the software automatically traced the contour of the endocardium at apical three, four and two-chamber views.
  3. At the same time, the general clinical data, demographic characteristics, electrocardiogram, chest CT results, troponin I (hsTnI) and brain natriol peptide levels on the day of echocardiographic examination were obtained through the hospital electronic medical record His system.
  4. Clinical follow-up was performed 12-18 months after the echocardiographic examination by phone and by electronic health record review. We recorded: 1) persistent cardiac symptoms, 2) interval presentation to the emergency department or hospitalization with cardiac symptoms, and 3) any major adverse cardiac event (myocardial infarction, stroke, revascularization, or death).

    The structural and functional parameters of the left atrial were obtained by conventional echocardiography, and the left atrial strain parameters were obtained by two-dimensional speckle tracking echocardiography.

Receives: Other: two-dimensional speckle tracking echocardiography

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Left atrial strain

    Myocardial strain derived from speckle-tracking echocardiography has been shown to be more sensitive and accurate in detecting subclinical impairment of cardiac function than conventional echocardiography. LV diastolic dysfunction could be explained by Left atrial strain.

    Measured: After recruiting, left atrial strain collected through software post-processing analysis will be assessed and reported up to 8 weeks.

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19 Pandemic, run by Haiyan Wang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Left atrial strain (time frame: After recruiting, left atrial strain collected through software post-processing analysis will be assessed and reported up to 8 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06170307, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2024.
